SPECIFICATION forming part of Letters Patent No. 'li' 968, dated November 29, 1904.

Application filed November H, 1903. Eel-ill No. 181,242. 'Ho model.)

To a]! whom it may concern:

Be it known that l. AnoUs'r (1' Ross. a citizen E of the United States. residing in Manhattan I borough, city of New York, in the county of New York and State of New York, have ini ventcdcertain new and useful Waterproofing- Sheeting for Buildings, of which the following is a specification. 4

This invention relates to means for waterproolingor clamp-proofing buildings and other structures.

ifhe invention consists in a sheeting which is made up of plies of fabric united by acompound that is adherent and. waterproof and which. moreover, remains for an indefinite length of time in a plastic condition. This sheeting may belaid between the lower and upper portions of a liner or as a lining for a side wall or a roof of a building or in rooting over a tunnc. and in a variety of other situatiors where it is desired to exclude moisture.

The accompanying drawing illustrates aroil of waterproofing-sheeting of the kind made the subject of the following description.

1 and 2 designate plies or sheets of unbleached muslin. paper, or other fabric, which i are united by an adherent compound 3, which is waterpri' oiand plastic'aud preferably forms a thin stratum between the plies of fabric. Said compound consists of asphalt or aspbaltum mixed with sutlicient pine-oil to render the compound plastic and preserve its plasticity andalso with sufficient linseed-oil to flux the asphalt and the pine-oil. Preferably lined, the heatrcquired being about 400:". It becomes a thick liquid, into which linseed-oil is slowly poured. 'lhen pine-oil is added, and the compound is stirred until it is thoroughly mixed. The compound is then applied to the fabric.

By the refining process the asphaltum is deprived of its impurities'and as well of acids and oils. The addition of the pine-oil, which is preferably distilled from the jim/x Austm/Zs, renders the compound plastic, which quality it retains for an indefinite time. The pine-oil is non-drying. The linsecd'oil favors the fluxing of tho asphaltumand pii'ic-oihani the three ingredients maybe employial in such i so that v proportions as to produce when inclosed between fabric sheets a sheeting which is waterproof and plastic and which can therefore adapt itself to corners and irregular surfaces without danger of breakingor tearing. Since the sheeting retainsits plasticity. it may be made up into rolls for the murkct and will be ready for use when required. Moreover, it can readily be applied by unskilled labor and without the necessity of heating it. It

is recommended that the pine-oil anti linseedoil be in about equal proportions and form about one-third, by weight, of the compound. In practice five hundred poundsof asplz-idtum are compounded with one hand ed and. twenty "5 pounds each of linseed-oil and pine-oil.

One of the principal advantages of my invention is that the compound is kept in a plastic condition, so that the sheeting may be bent alround or into sharp corners withoutliability of breaking, even though a long time has elapsed since its manufacture, while the plies of fabric are nearly inseparable and are absolutely ditmp-pro0f. The use of this compound favors the making up of thin waterproofing-sheets, which because of their thinness may be readily adapted to corners and folds where requiredwhile since the compound itself is waterproof it is not always, if

ever, necessary to saturate the fabric there- 8a with, thus leaving the sheeting clean, and conscquentl y ea y to handle. To some extent v;- riations may no resorted to without departing from the scope. of the invention.

The lining 3 l etwcen the sheets of fabric remains plastic for an indefinite length of time. The pine-oil is not only of advantage for the reasons already given, but is also itself waterproof. The sheeting is adapted to waterproof foundation-walls and other subterranean structures, where it is constantly attacked by water from springs and raiufalls, since it does not disintegrate under the action of water. The lining 3 is in the form of a thin stratum and is distinct from the fabric layers. although 9 5 adhering thereto and perhaps lilliugthe meshes of the latter. It is distinguished from amen-o paint, because the paint burdens and at the most is only ucoating or skin upon tlu' fabric,

hen the lattcr is stretched, as uflcll oo value in this connection also. since it readily .3'

nitcly-such pressures and remains absolutely occurs in bending the sheeting over sharp corners, the paint or skin is necessarily broken, whereas my lining 3 is distinct from the fabric, so that when the latter is stretched the lining does not break. but accommodates the g strctrhingof the fabric and remains absolutely waterproof; I I

YVhen used in foundstion-walls,waterproof in}; sheeting is often subjected to enormous pressure. which of course is not relieved soso iong as the building stands. Such pressure would of itself crush and disintegrate the-brittle paints or coathig's- 'iiereiofore employed in sheqtings of this dr'rscription, so that they would lose what slight capacity theyoriginally had for withstanding the constant pressure of water that is met in foundationwcrk, whereas my sheeting withstands indefiw'aterproof. The capacity of the lining for flowing is of great vsme when the sheeting is subjected to enormous pressu res, since the destruction of the sheeting is avoided.

The alternation of heat and cold to which building and tunnel walls are subjected has the-effect of expanding and contracting the walls. The plastic quality of the sheeting, and especially of the lining 3, lends it great adapts itself to expansion of the wall and remains impermeable, whereas the waterproofing material used in former shootings becomes brittle when cold and inevitably cracks during the expansion of the well, thus making openings for the water to leak in.

Having thus described my invention, I claim- 1. A manufactured article of commerce, consisting of a pliantwaterproofin -sheeting, which comprises plies of fabric, with an in terrening distinct strut-um of adhesive waterproof material which is in a condition of plasticity.

2. A manufactured article of commerce, consisting of a waterproofing-sheeting which is pliant when cold and comprises plies of fabric united by bituminous material which is in a substantially permanent pla tic condition.

3 A manufactured article of commerce, consisting of a waterproofing-sheeting which is pliant when cold and comprises plies'of textile fabric united by an adhesive waterproof mixture which is in a substantially permanent plastic condition; saidmixture comprising as phalt and oil.

4. A manufactured article of commerce, consisting of a roll of waterproofing-sheeting which is nliantwhen cold and comprises plies h of textile fabric, with an intervening distinct stratum of adhesive waterproof material oil which serves as a flux for said asphalt and ssid oil.

7. As a new article of manufacture, a waterproofing-sheeting comprising plies of fabric united by a compound comprising ssphslt and pine-oil.

8. As a new article of manufacture, a waterproofing-sheeting comprising plies of fabric united by a compound of asphalt, pine-oil, and a flux. i

9. As a new article of manufacture, I. waterproofing-sheetingcomprising plies of fabric I united by a compound. of asphalt, pine-oil and linseed-oil.

10. As a. new article of manufacture, a. na-

' terprooting-shceting comprising plies of fabric united by a compound of asphalt, piuebil and linseed-oil. the pine-oil and linseed-oil be-' ing in about equal proportions and forming about one-third by weight of the compound.

11. As a new article of manufacture, a waterproofing-sheeting comprising plies of fabric united by a. compound of asphalt with sufticient pine-oil to keep the article in a plastic condition and with sutlicient linseed-oil to flux the asphalt and pine-oil.

12. As a new article of manufacture, a waterproofing-sheeting comprising plies of fabric united by an adherent waterproof mix ure 10 whose base is a bituminous substance, such as asphalt-um, tar, pitci\ or the like, which is kept in a plastic condition by an oily substance which is' mixed therewith.

13. As a new article of manufacture, a wa- I 5 oil is fluxed with thebiturninous material by O means of u flll Xlflg-O!l.
